Same patient as in Fig. 1. a Plain radiograph at baseline without evidence for a loose prosthesis, b xSPECT Bone maximum intensity projection and c xSPECT Bone in combination with CT (CT with iMAR) at baseline as well. Periprosthetic SUVmax was 27.3 (black arrow) which was definitely above the cut-off value for a loose prosthesis (xSPECT Bone cut-off value: 14.78). Revision operation was refused. d Plain radiograph 2 years later showed a loose left prosthetic stem with progression of radiolucency around the femoral stem (white arrows) which correlates with pathological [99mTc]Tc−DPD uptake at baseline (b, c)
